3.2 HYDRAULIC SYSTEMS
The burner is designed to allow entry of the flexible oil-lines on either side of the burner.
H = difference of level; L = max. length of the suction line; I. D. = internal diameter of the oil pipes.
PRIMING PUMP:
On the system in fig. 5 it is sufficient to loosen the suction gauge
connection (6, fig. 4) and wait until oil flows out.
On the systems in fig. 6 and 7 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20 seconds
before repeating the operation.
The pump suction should not exceed a maximum of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from the oil. Oil pipes must be completely tight.
In the vacuum systems (fig. 7) the return line should terminate within the oil tank
at the same level as the suction line. In this case a non-return valve is not re-
q
uired. Should however the return line arrive over the fuel level, a non-return
v
alve is required.
This solution however is less safe than previous one, due to the possibility of
leakage of the valve.
■
It is necessary to install a filter on the fuel supply line.
The standard filter code 6276200 and that one with recirculation
code 6276201 are available on request.
■
The pump is designed to allow working with two pipes.
In order to obtain one pipe working it is necessary to unscrew the
return plug (2), remove the by-pass screw (3) and then screw
again the plug (2), (see fig. 4).
■
Before starting the burner make sure that the return pipe-line is
not clogged. An excessive back pressure would cause the
damage of the pump seal.

4. WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and
testing must be carried out observing the instruction manual of the boiler, including verification of the CO and
CO2concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
To suit the required appliance output, choose the proper nozzle and adjust the pump pressure, the setting of
the combustion head, and the air damper opening in accordance with the following table.
■ADJUSTMENTS FOR SIME BOILERS
The values shown in the table are measured on a SIME boiler (as per EN 267).
They refer to 12.5% CO2at sea level and with light oil and room temperature of 20 °C.
▲Burner adjustments carried out in factory.
In case of matching with a boiler different from the “Rondò-Estelle 6” model, for the adjustments fol-
low what indicated in the table.
■APPROXIMATE ADJUSTMENTS FOR INSTALLATION ON OTHER BOILERS
The values shown in the table are measured on a CEN boiler (as per EN 267).
They rfer to 12.5% CO2at sea level and with light oil and room temperature of 20 °C.
4.2 NOZZLES RECOMMENDED: Monarch type R ; Delavan type W - B

4.3 MAINTENANCE POSITION
Access to the combustion head, electrodes and nozzle, (see fig. 10).
➤Remove the burner out of the boiler, after loosing the fixing nut to the flange.
➤Hook the burner to the flange (1), by removing the combustion head (2) after loosing the fixing screws (3).
➤Remove the electrodes assembly (5) from the nozzle-holder (4) after loosing its fixing screw (B, fig. 11).
➤Screw the nozzle (6).
4.4 ELECTRODE SETTING
4.5 COMBUSTION HEAD SETTING, (see fig. 12 and 13, page 8)
This is done when fitting the nozzle, with the blast tube removed. It depends on the output of the burner and
is carried out by rotating the regulating rod, till the terminal plane of the blast tube is level with the set-point,
as indicated in the schedule.
In the sketch on fig.12, the combustion head is set for an output of 1.50 GPH at 12 bar, while the shutter is level
with set-point 3, as required by the above schedule.
Combustion head settings indicated in the schedule are valid for most cases.
The setting of the fan output according to the installation should normally be done only through the air damper.
Should one subsequently want to retouch also the setting of the combustion head, with the burner running,
operate on the rod (1) with a 6 mm spanner (2), (see fig.13).

TURNTOTHE RIGHT: (sign +)
In order to increase the volume of air entering the combus-
tion chamber and thus diminishing its pressure.
There is a reduction of CO2and the adhesion of the flame
to the air diffuser disc improves.
(Setting advisable for ignitions at low temperatures).
TURNTOTHE LEFT: (sign –)
In order to reduce the volume of air entering the combus-
tion chamber and thus increasing its pressure. The CO2
improves and the adhesion of the flame to the diffuser
tends to reduce.
(This setting is not advisable for ignitions
at low temperatures).
In any case do not bring the com-
bustion head setting more than one point away from that
indicated in the schedule. One set-point corresponds to 3
turns of the rod; a hole (3) at its end facilitates counting the
number of turns.
4.6 AIR DAMPER ADJUSTMENT, (see fig. 14)
The mobile air damper (1) operated by the jack (2) assures
the complete opening of the air intake.
The regulation of the air-rate is made by adjusting the fixed
air damper (3), after loosing the screws (4). When the opti-
mal regulation is reached, screw tight the screws (4) to
assure a free movement of the mobile air damper (1).
The settings, indicated in the table at page 6, refer to the
burner with its cover fitted and combustion chamber with
depression zero.
These regulations are purely indicative. Each installation
however, has its own unpredictable working conditions:
actual nozzle output; positive or negative pressure in the
combustion-chamber, the need of excess air, etc.
All these conditions may require a different air-damper
setting.
It is important to take account of the fact that the air
output of the fan differs according to whether the
burner has its cover fitted or not.
Therefore we recommended to proceed as follows:
➤Adjust the air damper as indicated in the table at
page 6.
➤Mount the cover.
➤Check smoke number and CO2.
➤Should it become necessary to modify the air output,
remove the cover by loosening the screw, adjust the
air damper, remount the cover and finally recheck the
smoke number.
4.7 PUMP PRESSURE
12 bar: The pump leaves the factory set at this value.
14 bar: Improves flame retention; it is therefore suitable
for ignitions at low temperatures.

4.8 BURNER START-UP CYCLE
Lock out is indicated by a lamp on the control box (3, fig. 1, page 1).
4.9 ADJUSTMENTS, TO AVOID FLAME - DETACHMENT, AT BURNER - IGNITION
This inconvenience can occur, when the temperature of the gas-oil decreases below +5 °C.
1) CORRECT POSITIONING OFTHE ELECTRODES, (see fig. 11, page 7).
2) PUMP - SETTING
The pump is factory set, at a pressure of 12 bar.
When the temperature of the gas-oil decreases below +5 °C, increase the pressure to 14 bar.
3) COMBUSTION-HEAD SETTING
Regulate the combustion-head one set-point further ahead than indicated in the instructions.
Example: the instructions require to set the combustion-head on set-point 3.
Instead, the setting is made on set-point 4.
4) FAN - AIR DAMPER ADJUSTMENT
Adjust the air damper of the fan, such as to obtain a smoke-number not inferior to 1.
(i.e. a combustion with the lowest possible excess-air).
5. MAINTENANCE
Burner requires a periodic maintenance carried out by a qualified and authorized technicians.
Maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and
consequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to the
burner acting on the main switch of the system.
THE BASIC CHECKS ARE:
➤Check that there are not obstructions or dents in the supply or return oil pipes.
➤Clean the filter in the oil suction line and in the pump.
➤Clean the photoresistance, (see fig. 9, page 5).
➤Check for correct fuel consumption.
➤Replace the nozzle (see fig. 10, page 7) and check the correct position of electrodes (fig. 11, page 7).
➤Clean the combustion head in the fuel exit area, on the diffuser disc.
➤Leave the burner working without interruptions for 10 min. and set rightly all the components stated in this
manual. Then carry out a combustion check verifying:
●Smoke temperature at the chimney; ●Content of CO2(%); ●Content of CO (ppm);
●Smoke value according to opacity smokes index according to Bacharach scale.

6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for some problems that could cause a fail-
ure to start or a bad working of the burner.
A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box
(3, fig. 1, page 1).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the
burner functions correctly, the lock-out can be attributed to a temporary fault.
If however the lock out continues the cause must be determined and the solution found.
WARNING
The manufacturer cannot accept responsibility for any damage to persons, animals or property due to error in
installation or in the burner adjustment, or due to improper or unreasonable use or non observance of the
technical instruction enclosed with the burner, or due to the intervention of unqualified personnel.
